My recent purchase of a number of 22lr, CCI 525 rd Blazer bulk box's...are coated with heavy duty lube wax. After like shooting 30-50 rounds in my match grade chambered Kimber Classic --- I have failures to eject, with the round stuck in the chamber. I have to press down on the extractor bar, to get the spent or live round to eject. After that...I swab out the chamber with a Q-Tip soaked with degreaser --- then a dry one.
